I did this walk in June 2011 at the end of the 2011 Pilbara trip . It can be done
over four days at a fairly relaxed pace, but see my
warnings above about weather and terrain. The main attractions are the
side-gorge exit from Dales Gorge, the plateau across to Munjina Gorge and the
upper reaches of Munjina Gorge. The geology in those two small gorges is as
weird and diverse as you're likely to find anywhere. They contrast with the
intervening plateau with its spinifex, termite mounds, flowering shrubs and
trees. You'll need the following 1:50,000 topographic maps:

Mount Windell 2652-4

Mount George 2653-3

The start of this walk retraces in reverse the early stages of the 2008 Munjina to Bee Gorge walk. On the 2008 walk we ended up
having to swim a large pool as we approached the Circular Pool turnoff, but
this time we discovered that by sticking to the northern bank we could get past
the pool with dry feet. We had a fairly late start on day one after exploring
the day-walk areas around the upper end of Dales Gorge. so the first campsite
was basically on the first patch of reasonably flat, dry ground that appeared
as the light was failing.

Day two took us past Dignum Gorge and down to a nice campsite at the
exit-gorge junction. There was a reasonable supply of running water here,
although this might not be the case in a dry year or later in the season. Not
being in a rush to get anywhere, and having budgeted time for photography, we
spent day three here too.

Day four saw us walking up the exit gorge, across the plateau and down into
the Munjina Gorge tributary. We made camp at the edge of the creek bed at the
junction of a south-western tributary. This was a pleasant campsite, but
judging by the flood debris in the trees nearby and the sculpted mounds of
gravel here, this would be a fairly bad place to be if any significant rain
fell. Although the weather was fine, we camped on the edge of the creekbed and
had easy access to higher ground just in case.

The original plan for day five was to follow the gorge out to Figtree
Crossing to meet the highway, but at the junction with the eastern branch of
Munjina Gorge we reassessed that. The eastern gorge was swampy, knee-deep in
flood debris, waist deep in reeds and thick with paperbarks. We pretty much all
decided right there to scuttle up to the southern rim and make our way out
along that. From that vantage point we could see that the gorge looked like
pretty slow-going all the way along.
